RE: Deer rifle for small girlfriend
I would look at Ruger they make very good guns for a lot less than Browning and Remington. Of the calibers you listed I would get the 7mm-08 or even the 7x57 mauser which is compairable to the 7mm-08. Both have a lot less recoil than a 30-06 and only go about 200 fps slower. Both are more than capable of killing a deer out to 250 yards. Some of the smaller calilbers would work too but I would try to go a bit bigger. You don't judge a caliber on how well it preforms on a good shot, but how it preforms on a bad shot.
